9. Promote “Almost Gone” Items in Wishlists

When stock is low for a wishlist item, it gets a bold “Only a Few Left” label or a similar alert that draws the customer’s eye. To ensure these items don’t get overlooked, they’re often shown at the top of the wishlist with an urgent message or color-coded warning, like a red tag or icon.

Examples of “Almost Gone” Items in Wishlists:

In the image below of Sephora, you can see a “Get These Before They’re Gone” section, featuring products from brands like Valentino and TOM FORD. Each item shows an “ONLY A FEW LEFT” alert, highlighted in red, making it clear that stock is limited. Placing these items right at the top of the wishlist subtly nudges customers to act fast before these items are gone for good.

10. Show Cart Cross-Sells for Out-of-Stock Products

When a product in a customer’s cart goes out of stock, the cart automatically displays a cross-sell section labeled with something like “Shop Similar” or “You May Also Like.” This section suggests similar products, such as items with the same style, color, or function, so customers can easily find a replacement without leaving the cart.

Examples of In-cart Cross-Sells for Out-of-Stock Products​:

Look at this example of Wayfair! They prominently displays a message in the cart to inform the customer, stating that the item is unavailable and providing the option to either “Remove” or “Save for Later.” This ensures transparency and keeps the customer informed.

Just below the out-of-stock item, Wayfair shows a “Compare Similar Items” section. This is where they strategically place alternative poufs or furniture pieces that resemble the original item.

Recommended Shopify In-cart Cross-sell Apps:

11. Send “Almost Gone” Emails for Low-Stock Items in Cart

When a customer leaves an item in their cart but doesn’t complete the purchase, it’s a perfect opportunity to gently remind them of what they’re about to miss. By sending a well-timed “Almost Gone” email, you can alert customers if an item in their cart is running low on stock.

You can further enhance this email by showing alternatives or similar products, increasing the likelihood that the customer will still make a purchase even if their original choice is no longer available.

Examples of Sending “Almost Gone” Emails for Low-Stock Items in Cart

Take a cue from Nine West, who has mastered this tactic. When a customer leaves an item in their cart, Nine West sends an email that not only informs the shopper that the item is almost sold out but also includes a “check availability” button. If the item has already sold out, they offer similar, visually comparable products as alternatives. This personalized nudge not only helps clear out inventory but also keeps the customer engaged with other relevant products.

For Shopify merchants, we suggest these 2 popular tools, Klaviyo and Omnisend can help you seamlessly automate this process. These email platforms allow you to set up flows that automatically trigger when a cart is abandoned or when a product is running low on stock.

12. Always Provide Variant Fallbacks

Ever clicked “Add to Cart” only to be met with a disappointing “Sold Out” message? It’s a major bummer, right? Enter variant fallbacks. These little heroes automatically suggest similar products when your first choice is unavailable. Imagine you’re eyeing a pair of blue sneakers in size 10, but they’re out of stock. A good e-commerce site will quickly offer you size 9 or 11 in blue, or maybe a different color in size 10.

Recommended Apps to Send Automatic Emails for Low-Stock Items

After testing a range of apps designed to manage product variants effectively, we’ve found that both Globo Product Options and Infinite Product Options stand out as good choices for providing variant fallbacks on Shopify stores.

  • Globo Product Options, Variant lets you add unlimited variants and product options (like swatches and dropdowns), and automatically shows alternative variants when one is out of stock.
  • Infinite Product Options enables a wide range of customizable options and variant fallbacks, with the ability to bundle add-ons and display alternatives using conditional logic.

13. Add Low-Stock Flags to Boost Conversions and Prevent Disappointment

Prevention is the best cure when it comes to managing low stock. Alerting customers to low-stock items in real time can help increase urgency, boost conversions, and reduce the likelihood of disappointment during a future visit. When customers see that a product is in limited supply, they’re more likely to act fast, reducing the chances of cart abandonment or missing out on a desired item.

However, the key to effectiveness lies in how you present these low-stock alerts. Stock messages that are hard to find or easily overlooked won’t create the sense of urgency you need. For example, using black text in a subtle location, such as near variant chips, can make the alert easy to miss.

Examples of Sending “Almost Gone” Emails for Low-Stock Items in Cart

A great example of this strategy is Alo Yoga, which displays an ‘Almost Gone’ flag when a color variant is running low on stock. This message appears prominently on the product list, right when customers are selecting their color options. This helps create urgency without being too intrusive, pushing customers to complete their purchase before the item sells out.

  • Note: The flag works well for color variants, but doesn’t include size variants, so keep this in mind when implementing similar alerts on your store. Also, this feature is available on desktop but could be extended to mobile in the future for broader reach.

14. Split Payments for Preorder Products

One barrier customers often face with preorders is the upfront cost. For items that won’t ship right away, some shoppers are hesitant to pay the full amount upfront, which can lead to hesitation or lost sales. To tackle this, offering split payment options for preorder products is a highly effective strategy to drive conversions while meeting customers’ financial preferences.

Imagine a popular limited-edition product launch—perhaps a designer bag, a high-end tech gadget, or an artisanal home décor piece. By enabling split payments, you give interested customers the opportunity to “lock in” their purchase with a smaller deposit, while they anticipate its arrival and prepare for the final payment. This split payment model not only increases affordability but also enhances the shopping experience, making it feel more exclusive and accessible.

15. Offer Discounts for Preorder Items

One powerful tactic for keeping customers engaged, even when products aren’t immediately available, is to offer exclusive discounts on preorder items. By providing a limited-time discount on preorders, you’re not only incentivizing customers to buy early but also creating a sense of exclusivity around your products.

partial payment with discounts

This strategy is widely used by brands looking to create buzz around product launches or high-demand items. For example, if you have a best-selling product that’s temporarily out of stock in certain variants, offering customers a small discount or a partial payment option can help secure their purchase without losing the sale. This approach not only generates early sales but also builds excitement with limited, preorder-only offers.

Just be sure to provide an estimated arrival date to build trust and keep customers informed about when to expect their order. This transparency reassures them, enhancing both their confidence in your brand and their overall shopping experience.
